I imagine you would have spotted this though because it is normally on the drive label. Yes, the two 'lower' members of this drive's family to have this feature. However, per the spec manual the dpea-31080 has this 504mb geometry feature disabled. Says that jumper position 7 (pins 13-14) is ignored. Hmm. I wonder :) Is it actually sharing the ide cable with another drive or is it by itself? Sometimes the older drives had to be jumpered for Single instead of Master. Just now the hd is on the Master connector (set for CableSelect) and the CDROM is on the Slave connector (set for CableSelect). The next test will be to remove the 'CableSelect' option and promote each device to its' own position. Suspect I might have been testing whether CS works or not. Perhaps not with this bios.. :) Obviously a 440BX chipset board should handle a 1gb drive. I think that one was new enough to go up to the 32gb barrier or possibly the 137gb barrier. Seems logical, but back in 1998 when this m/b was new, IIRC, a 40GB had was a really big deal. And a 137GB hd was just a dream! My how time flys. And technology marches on. If you enter CMOS utility and use the Auto Detect IDE option does it display the values it is detecting for the sector, head, cylinder, disk type, etc. ?? Is it LBA, CHS, or LARGE mode? Now this gets to most for my present confusion. For SG's I did use the Auto Detect IDE option. What I received for the hd was/is a bit queer. I get the small read window with: Select Primary Master Option (N=Skip) : [] Options SizeCylsHeadPreComp LandZ Sector Mode 2(Y)1083525 64 0 209963 LBA 1 1083210016 65535 209963 NORMAL 3 1083525 64 65535 209963 LARGE Obviously, I choose the one that matches the hd's spec'd geometry. That would be (1). Confused by why choice #2 has (Y) appended. Also notice the even though this detect routine seems to acknowledge the CDROM, when I go back to the base cmos screen, the primary slave line indicates that there is nothing present. Not quite Bios-Hell, but close. What happens if you force LBA, CHS, or LARGE and leave the geometry details set to Auto? This I will try in a bit. Except I think that if I leave the details set to Auto, I can not force any of the values. From what I see, if I choose Auto, bios rules. Go into FDISK and look under NON-DOS Partitions (#4 i think)?, anything there? Try using FDISK /MBR at the command prompt of your DOS boot disk to rewrite the master boot record. Yes, this I will try also. Though, in all these years I have never been able to get this command to work. Will try again. It doesn't really matter I suppose, but I'm having trouble understanding why are you dealing with DOS and trying to get a pretty ESCD table in the first place? Perhaps just my own stupid pig-headedness. I grew up in computers learning that it was best if devices in the ESCD table had their own IRQs to use. And, way back then, some devices liked some IRQs better than others. Now, I suppose this is just so much folklore and habitual ritual. Nothing more. I thought you were gonna run FreeBSD or Linux?? Yes, that is what I will do eventually. The first install try got goofed up by me. It started booting with more that a few command line screens that indicated something went badly wrong. I am starting over. And, part of it is finding the hd dorked up partition-wise, install-wise, pebcak-wise. :) When all else fails, I retreat to the last known OS I could sorta drive. That be MS-DOS. I'm drawing upon neurons that were formed during late grade school and jr. high. Not quite sure if that makes me feel young or old. ;) We are as young and old as we feel. Put the neurons to nap mode. I mean you no harm with this. Have another EggNog! Merry Christmas! This is goof-off project for me. If it does not work, well, my test of FreeNAS just ends and I'll find something else. Or, maybe just buy some newer hardware :) Best, Duncan -Tharin Olsen DHSinclair [EMAIL PROTECTED] wrote: MS-DOS does not seen the hd any differently. Still 504MB.

[H] EIDE-speak?
Am I correct: Old EIDE: Black connector (m/b) - Black connector (master) - Black connector (slave) Pata EIDE: Blue connector (m/b) - Gray connector (master) - Black connector (slave) Still wondering about the plugged pin in the m/b connector. Have lots of these. Can not use them. My m/b has a pin where it should not be. Best, Duncan
Re: [H] EIDE-speak?
All IDE devices/cables are parallel ata. The Blue/gray/black cables you have should be the ATA 66/100 rated cables with 80 conductors/wires. The older style only had 40 but was only good up to ATA 33. Black (far end of cable) is master and gray (middle connector) is slave. You are right about Blue being for the host controller. Pin 20 should be the one that is plugged on your cables. You might be able to remove it with a pick if it isn't actually molded that way. Newer drives and motherboards have that pin removed and the cables are keyed as such. It was also like that on early compaqs, dells, etc. I remember having lots of pulled cables from those kind of systems and not being able to use them on whitebox motherboards or drives because they weren't keyed. The Tier1's seemed to like have their cables keyed, I guess they couldn't put stuff on backwards at the factory that way. -Tharin Olsen DHSinclair [EMAIL PROTECTED] wrote: Am I correct: Old EIDE: Black connector (m/b) - Black connector (master) - Black connector (slave) Pata EIDE: Blue connector (m/b) - Gray connector (master) - Black connector (slave) Still wondering about the plugged pin in the m/b connector.

Black (far end of cable) is master and gray (middle connector) is slave. You are right about Blue being for the host controller. Yes, all my research today gets right to this. The funny part is the m/b (bios) does not seem to recognize the hd or the CDROM, though it does seem to use them. Depending on what I ask to be done. Hmm! Pin 20 should be the one that is plugged on your cables. Yes, pin 20 is plugged in all the SPARE EIDE cables I own. The problem is that pin-20 is NOT missing on my m/b! Pin-20 is clearly sticking up and staring at me. OK. I am now testing a modified EIDE cable. I cut out, dug out sorta, well, trashed a brand new (?) EIDE cable to test this pin-20 business...

Re: [H] EIDE-speak?
Some of those drives had a jumper to force the 504mb drive geometry for compatibility. I imagine you would have spotted this though because it is normally on the drive label.
